A Device I/O Error is an error that occurs as a result of using a peripheral device such as an external hard drive. I/O means an input or output error that is caused by a driver that is outdated or not yet enabled. The device driver is a necessary component for allowing your operating system to control and communicate with the peripheral device. When a Device I/O Error occurs your PC is unable to set up the software that is needed to configure the device driver and operate the peripheral unit.

There are many different factors that can cause a Device I/O Error so you can begin to find the problem through a few basic troubleshooting steps.

•Find the Device: To locate the device that is causing the error, click on "Start" on the main toolbar of your desktop and then choose "Control Panel" from the menu. When the Control Panel opens, select "Performance and Maintenance" and choose "System." When the window opens choose "Hardware" and then click on the "Device Manager." Locate the device that has a red "x" marked on it. Click on the "General" tab and then choose "Enable Device" and click "OK." If there is still an error proceed to click on "General" and then choose "Troubleshoot" and click "OK."
•Update the Driver: Go to Garmin page and download the latest drivers.
